ATLANTIS MK II
The ATLANTIS has been consistently designed for optimum sound-pressure rating while retaining a moderately sized cabinet and an elegant appearance. In the bass range, two AL 170 - 8 OHM are mounted in parallel but in separate housings, where each has about 27 l of air space to itself. These speakers have a lower limiting frequency of 28 Hz meaning that they generate good, solid deep bass. Where you position the speakers is more or less a matter of choice, but they should not be right against the wall (a minimum of 10 cm is needed) as otherwise the effect of the bass reflex tubes will suffer.
Compared with the 'normal' AL 130 - 8 OHM, the AL 130 M - 8 OHM is equipped with a shorter voice coil. This improves efficiency and makes it the ideal choice in this combination.
Used as a tweeter, the KE 25 SC - 8 Ohm is activated from 2500 Hz. The distortion factor of this ceramic dome driver is really low at these frequencies, so that even high volume levels come across completely free of distortion.
